Abstract

The booster bending magnets for the Swiss Light Source (SLS) at PSI include dipole, quadrupole and sextupole field components. The two types of magnet, focusing and defocusing, are laminated for operation at 3 Hz in the booster synchrotron, The 2D pole profile has been optimised with the smooth shimming method developed by the PSI Magnet Section. The 3D fringe field effects have also been computed. The prototype magnets were manufactured with removable pole ends to allow various end cuts to be measured. The prototypes were magnetically measured at the standard PSI measurement facility. The analysis, performed using the mid-plane field maps, confirmed the good field profile quality and helped determine the final pole end cuts for the magnet series,.
